Richard Cogdell - Bacterial Photosynthesis (MWV 069)

submitted by: MicrobeWorld
Richard Cogdell is the Director of the Institute for Molecular Cell and Systems Biology at the University of Glasglow, Scotland. Richard was led to a career in studying bacterial photosynthesis by a desire to learn and understand basic photosynthesis, he "wanted to know how natured worked." In 1995, Richard's research group, in collaboration with others, used protein crystallography to determine the three dimensional structure of a light-harvesting complex from the purple bacterium,...

Targeted Gene Identification from Short Gene Fragments in Metagenome and their Use in Biogeochemical Studies

submitted by: dougramsey
Metagenomics allows for a new approach to studying biogeochemical processes in an environment, by giving an approximation of a community’s biogeochemical potential through the genes involved in a given process. Lipid biomarkers are well suited to this kind of approach because they are important for a number of biogeochemical questions and some have well studied biosynthetic pathways. One important class of lipid biomarkers, triterpenoids, were investigated in a new metagenomic sample that...

Bacterial Inclusion Bodies Contain Amyloid-Like Structure

submitted by: apryl
Protein aggregation is a process in which identical proteins self-associate into imperfectly ordered macroscopic entities. Such aggregates are generally classified as amorphous, lacking any long-range order, or highly ordered fibrils. Protein fibrils can be composed of native globular molecules, such as the hemoglobin molecules in sickle-cell fibrils, or can be reorganized β-sheet–rich aggregates, termed amyloid-like fibrils. Amyloid fibrils are associated with several...
